PATENT. OFFICE I nonnnr M. J'ALCKSON, or LAKE oRnEK 'rnxAs ATTACHMENT FORISEEDAPLANTERS if 7 Application filed Ma 19 i This invention relates particularly to an attachment which is adaptedto be suspended 7 below a seed hopper ofthestandard planter, such for instance as a cottoneseed planter, 'whereby seeds maybe periodically distributedin the travel of the planter. The present invention has been particularly designed to accommodate itself to a planter of the standard type and to permit the attachment '10 thereof with a minimum amount of effort;

, 7 Anobject of the invention is toprovidean attachment. that functionsv in conjunction v withthe seed hopper of the planter to receive J the proper supply of seeds from the hopper and then periodically" deposit the same.

An object ofthe invention is the novel 7 compact arrangement of'the component parts for direct operation from the axle of the planter. Y I A feature of the invention is thenovel con 7 struction of the distributor and its associated parts so as to be periodically operated in the continuous travel of the planter over the Besides the .above my invention distinguishes in two sets of mechanismone con tinuously operated by the axle of the planter vin the travel thereof and the other periodir 'cally operated by the continuous operated 'mec'hanism. a

With these and other objects in view the invention will be better understood from the detail description taken in connection with the accompanying drawing, wherein {Figure 1 is a side elevation of a t-planter showing my attachment applied thereto, 1 Figure 2 is a rear elevation,

Figure 8 is-a top plan view,

, 7' v Figures is a longitudinal sectional view,

' "I Figure 5 is a detail view of one of thetrips. i 1 Again referring to .the drawings illus-i I trating one of the -many constructions of my invention the numeral 1 designates a frame including the side bars 2 and the cross bar 3.

The side bars 2 carry the clips 4 by means 1 of which the frame is rigidly secured, in verr tically suspended position to a stationary porv *tionof theplanter B. The cross bar 3 supports a chute 5 of U-shaped formation in cross section to provide the'open rear side to which is secured a double arm trip 16 so 4 the ground the gate will be periodically 1927. Serial no. 192,731.

6 to accommodate the gate 7 that rigidly be noted that when the gate? is in closed position within the chute it extends at an angle to provide a tapering pocket 9 for the reception of the seed delivered from the spout C of the hopper D. I a

As shown in Figure 5 the rod 8 has secured thereto a trip 10 consisting of a collar 11 from which projects the arm 12 and lug 13,- the' latter in turn securedto a contractile spring 14: connected to the frame. The spring 14 is utilized to resiliently hold the gate in closed position as shown in Figure 4 so asv to support the seeds until they are released by the operation of the gate by the operating mechanism now to be described. Also journaled in the sidebars 2 is a drive shaft 15 positioned that in the rotary movement thereof the arms will intermittently strike the arm 12 for periodically moving the gate to opening position. v

' The shaft 15 may be operated in various manners but in the drawings I have shown the shaft provided with a direct drive con- "nectionwith thev axle C of the planter so that in the'movement of the planter over moved to open position with the result that the seeds are uniformly distributed over the ground, As illustrated in the drawing, a small gearl'? is fixed to the shaft 15 and constantly meshes with aflarge gear 18 fixed to the itXl/C. T I

From the foregoing description taken in connection with the drawings it will be appreciated-that in the travel of the planter over the ground the drive mechanism con- 9 sisting of the shaft 15 and gears 17 and 18 will be continuously operated with the result that the arm of the trip 16 will intermittently strike the trip 10 for giving intermittent rocking movement tothe rod 8 for periodioally moving the gate to open position to drop the seeds which have been previously deposited in thechute. 'It is of course to be understood that the various parts may be designed in variousother manners than illus- 1 shaft carryingsaid flap valve for depositing below the spout of the usual seem-hopper thereof com risin a broad flat transverse 7 b J 7 J downwardly extending apron-like supporting frame member, having upwardly extend-v ing side bars integral therewith means for detachably securing said ibars .ito the' axle oft the planter, an intermittent delivery chute positioned-beneath the ispout of the seedrhopper comprisinga box having its rear verti cal wall rigidly-secured in'engagement with the'said-apron for the major portion of its length whereby a firm support is obtained,

an oscillatingshaft extending through the side walls of-the delivery chutebox and jour-. naled in the side bars of said apron, a flap valve within said box and mounted'on said oscillating shaft, resilient means tending to hold the flap valve in closed position, and a second shaft likewise journaled in the said sidebars and actuatedfrom the axle of the planter for intermittently oscillating the seed. I

In testimony whereof I aflix my'sig'nature,

'ROBERT M. JACKSON.
